31 Claims.

Our invention relates to a railway draft arrangement and especially tonovel bumng and drafting means designed to be associated with a couplerof the type described in detail in Patent 2,271,770, issued by theUnited States Patent Ofnce on February 3, 1342, to Edmund l?. Kinne.

The general object of our invention is to devise a draft arrangement forsuch a coupler incorporating features for centering the coupler andholding it level without the use of separate carrier means.

Our novel arrangement incorporates front and rear followers withresilient means compressed therebetween and auxiliary' resilient meansso arranged as to maintain the. coupler in its normal position or toreturn it to normal position upon horizontal or vertical anglingtherefrom.

O ur novel structure also contemplates an arrangement w-herein thecentering and leveling device for the coupler may be used withoutresilient drafting means,.if desired.

In. the drawings, Figure 1 is a top plan view of our novel form of draftarrangement shown as applied between the draft sills of a `car structure(otherwise not shown).

Figure 2 is a side elevation, partly in section, of the structure. shownin Figure 1, the section being taken approximately in the verticallongitudinal plane indicated by the line 2-2 of Figure l.

Figure 3 isa fragmentary view corresponding to the showing oi Figure 1but illustrating ahorizontal angling. of. the coupler..

Figure 4. is. a. fragmentary view corresponding to a, portion of Figure2 while. illustrating vertical angling.

Figure 5. is a sectional. view through the draft connection,l the.section being taken in the vertical transverse plane. indicated bytheline 5-5' of Figure. 2.

Figures d to 9 inclusive are. views of our novel form of. connectingbolt.. Figure 6 being. a top plan view with a portion of the stern outaway, Figure 7. a side elevation, Figure 8` an; end view taken from theleft as seen in Figures (i and 7', and Figure 9 a sectionalV viewthrough the pin opening, the.. section being taken approxirrrately inthe horizontal plane bisecting the pin opening and as indicated by the,iine. 9".--3l of. Fig-ure 7.

Figures. l0 to 12 inclusive showin detail my novel form of bearingbloeitl Figure 10 being a top plan, Figure Il a. front elevation takenfrom the right as seen in Figure I0', and Figure l2 a sideelevationtaken from the bottom as seen in Figure 10.

Describing the structure in detail, our novel arrangement comprises thespaced sills 2, 2, forming a portion of a car body (not shown), saidsills comprising the rear draft lugs 4, 4 and the front draft lugs 6, 6of usual type. Seated respectively against said front and rear lugs maybe the front follower ii and the rear follower i0 with the compressionspring |2 confined therebetween. Bearing against the front follower 8may be the butt end I4 of the coupler I6, said butt end having a datvertically arranged central face, seating as at I8 against the frontfollower 8 and having vertical arcuate portions at either side of saidflat face, and seating as at 20, 20 against the vertical ribs orshoulders 22, 22 (Figure 3), said shoulders having surfacescomplementary to the adjacent portions of said coupler butt in order toaccommodate its seating thereagainst. The shank or butt portion I4 ofthe coupler I6 is formed, with a. horizontal slot 23, flaring at bothends as Well shown in the sectional view of Figure 2, within which maybe received the relatively flat head portion 24 of the tail bolt,generally designated 26, said head portion being horizontally tapered asat 21, 21 fore and aft of the pivot point 28 as well seen in the sideview of Figure 'I to acA commodate the head 24 in the slot 23 invertical angling of the coupler. The head y24 may be formed with avertical pin opening 30 through which may pass the pivot pin 32 (Figure2), said pivot pin also extending through the vertically alignedopenings 34, 34 formed in the shank or butt I4. The rear wall of thetail bolt' pin opening 30 may lbe tapered above and below the horizontalaxis of said bolt as seen at 36, 36 (Figure 7) to accommodate saidvertical angling and the forward Wall of said opening 30 may be cut awayas at 38 (Figure 9) to form an arcuate seat for the bearing block,generally designated 40 (Figure 10) which may seat as at 42 against thepivot pin 32 and as at 44 against the beforementioned recess at 38, saidblock 40 thus accommodating horizontal and vertical angling of thecoupler with respect to the tail bolt 26. y

The bolt 26 may extend through the central opening 46 in the frontfollower Which may :be reinforced by the annular flange or boss 48,afiording positioning means for the main compres-- sion spring l2. Thesaid bolt 26 may also extend through the central opening 5W in the rearfollower lwhich may' aord a seat as at 52 for said spring l2. Theopening at 5U' may be large enough to accommodate the bossi 54 formedvon the inner end of the securing' nt 56,. said. nut 56y being spacedrearwardly of the rear follower fr and providing a lost-motionconnection between the bolt 26 and the followers. The boss 54 affords onits inner end an annular seat as at 58 for the inner spring 60 which isthus compressed between said securing nut '56 and the front follower 8.It will vbe understood that this inner spring 60, applied under pressurebetween the front follower boss 48 and the nut 5E, exerts a force tohold the coupler butt I 4 against the front follower, seated at I8, 20,and resists any angular movement of said coupler, whether vertical orhorizontal Within the period of lost motion between bolt 26 and thefollowers.

In Figure 3 is illustrated the condition that takes place underhorizontal angling wherein it may be noted that the coupler butt I4 isfulcrumed as at 62 against the face of the front follower 8, a cornerradius of the coupler shank being seated against said front follower atone side of the center line of the gear. This angling action has furthercompressed the center spring 60 due to the pulling of the tail bolt in aforward direction so that the securing nut 56 is seated as at E4 againstthe rear follower I0. The expansive force of the spring 6i) thus isoperative to return the vcoupler to its normal central position asillustrated in Figure l.

The condition which occurs upon vertical angling is illustrated inFigure 4. Here the cou pler is angled downwardly and the extension 66 onthe lower rear edge of the coupler butt is fulcrumed as at 68 againstthe front follower 8 while'the bolt 26 is again pulled forward so thatthe nut-B is in close proximity as at 70 to the rear follower l0. As inthe condition of Figure 3, the auxiliary spring 60 is compressed and theexpansive force of said spring exerts pressure to pull the coupler buttback into full engagement with the front follower, as illustrated inFigure 2.

From'the above description, it will be apparent that the action of thecentering and leveling means is independent of the main compression ordraft spring I2 and, if desired, the centering and leveling device maybe used independently of the draft spring. In other words, if desired,the draft spring may be omitted entirely. In such case, the frontfollower 8 would be a xed member instead of a movable member and thedraft spring l2 would be replaced by a rigid member of length equaltothe solid height of said spring l2.

The detail of the tail bolt is shown in Figures 6 to 9 inclusive,wherein it may be noted that the threaded end 12 may be slotted as at 'Mto accommodate the retaining bolt 16 (Figure 2) which may hold the nut56 against rotation of said Vbolt and permit adjustable positioningthereof.

The pin bearing block 40 is shown in detail in` Figures to 12 inclusiveand may be seen to be of arcuate form with the cylindrical face 42 onits inner radius for full bearing against the pivot pin 32, said blockpresenting at its outer radius a spherical seat as at 44 for bearinglagainst the complementary base on the head of the tail bolt as at 38, asalready described.

It will thus be seen that in our novel arrangement we have providedresilient means for accommodating both vertical and lateralangling ofthe coupler in normal use thereof while at the same time maintainingsaid Lcoupler in horizontal position where service conditions permit.

It is to be understood that we do not wish to be'limited by the exactembodiment of the device shown, whichis merely by way of illustrationand not limitation as various and other forms of the Vdevice will, ofcourse, be apparent to those skilled in the art without departing fromthe spirit of the invention or the scope of the claims.
